A Thermoelectric Modules Voltage Monitoring System Used in Automobile Exhaust Thermoelectric Generator

摘要

According to the requirement of independent voltage monitoring of thermoelectric modules used in Automobile Exhaust Thermoelectric Generator (AETEG) designed by our group, a kind of voltage monitoring system based on master-slave architecture that includes several slave detecting boards and a master detecting board was designed in this paper, the hardware schematic and software flow diagram were provided, the amplifier circuit that could detect negative voltage of thermoelectric modules was designed, and the PC based monitoring interface using VC++ language was developed as well. The practical application results validate that the system designed is sophisticated and steady, it meets the real time voltage monitoring demand of thermoelectric modules and provides convenience for their optimization of electric topology structure in future.
